The invention relates to the technical field of intelligent traffic technology, and discloses a multi-sensor fusion method for road condition measurement, which comprises the following steps: S1, millimeter-wave radar and laser radar detectors are arranged in front of different lanes of a road to measure the distribution and driving speed of vehicles and the azimuth angles of the vehicles; S2, vehicle state information including vehicle distribution and speed information is displayed to a driver through a front LED screen display unit; and S3, when a front-end monitoring unit detects that the distribution and the speed of the passing vehicles are abnormal, an RGB camera is used for capturing pictures of the abnormal vehicles, and meanwhile, an audible and visual alarm is started to give an alarm and guide the passing abnormal vehicles. According to the multi-sensor fusion method for road condition measurement, accurate measurement of vehicles, pedestrians, roads, warning signs and the like in a current area is realized by arranging a plurality of sensors such as millimeter wave radar, laser radar, an RGB camera and the like, and accurate road condition structured information of the current area is formed.

本发明涉及智能交通技术技术领域，且公开了一种面向路况测量的多传感器融合方法，包括以下步骤，S1，通过毫米波雷达、激光雷达检测器安装在道路不同车道正前方，用于测量车辆的分布和行驶速度、车辆的方位角；S2，通过前方LED屏显示单元通过车辆状态信息，包括车辆分布和速度信息，将信息显示给司机；S3，当前端监测单元检测到通过车辆分布和速度存在异常时，利用RGB相机抓拍异常车辆图片，同时启动声光报警器对通过的异常车辆进行报警和引导。该一种面向路况测量的多传感器融合方法，通过是设置毫米波雷达、激光雷达、RGB相机等多种传感器，实现对当前区域内车辆、行人、道路、警示标志等的精确测量，形成当前区域精确的路况结构化信息。
